Celestial Prominences

The NGC 3582 nebula sits inside of the star forming region called RCW
57. The massive loops of ionized gas expelled by dying stars remind
me of solar prominences. This image is comprised of data taken on the
2.2m scope at La Silla with the WFI instrument on June 16, 2002.
Having only 2 channels of data to work with inspired some
non-traditional color work.

7 x 5 min with H-alpha filter4 x 30 s with Broadband Rc filter

Image was de-biased and flat fielded using IRAF with the esowfi tool.
Channels were combined using PixInsight as:

red = halphagreen = 0.25*halpha + 0.75*Rcblue = Rc

Combined channels were further processed in Photoshop to remove
instrumental artifacts and tweak colors and crop.

Hello, this is the blind astrometry solver. Your results are: I'm sorry to say that I couldn't solve your system. However there is some good news! Someone should be around soon to solve your image by applying a few tweaks. We'll let you know how that goes.
